The Importance of Modeling Exceptions

The example I usually give there is like, if you have, let's say, an e-commerce application and you have to keep track of stock of products. So make, turn this into a signal that after like you, you cross a certain threshold, you'd have to do other business activity to solve that problem. The easy naive approach is just to throw the exception and let the caller deal with it. That's not necessarily in line with what the business needs are.
